java - 如何使用扩展权限创建 Facebook session

Question

如何在 facebook sdk 3.0 for android 中创建具有扩展权限的 facebook session ？

Answer 1

您必须先登录用户。然后当您需要扩展权限时，请执行以下操作:(我已将其用于发布权限)

private static final List<String> PERMISSIONS = Arrays.asList("publish_actions");
private static final int REAUTH_ACTIVITY_CODE = 100;
// Check for publish permissions    
List<String> permissions = session.getPermissions();
if (!isSubsetOf(PERMISSIONS, permissions)) {
    Session.ReauthorizeRequest reauthRequest = new Session
           .ReauthorizeRequest(this, PERMISSIONS)
           .setRequestCode(REAUTH_ACTIVITY_CODE);
    session.reauthorizeForPublish(reauthRequest);
    return;
}

isSubsetOf():

private boolean isSubsetOf(Collection<String> subset, Collection<String> superset) {
  for (String string : subset) {
     if (!superset.contains(string)) {
         return false;
     }
  }
  return true;
}
